As a Christian, it makes sense for 7OwO to be against lgbtq. Romans 1:26–27 in the King James Bible says “26For this cause God gave them up unto vile affections: for even their women did change the natural use into that which is against nature: 27And likewise also the men, leaving the natural use of the woman, burned in their lust one toward another; men with men working that which is unseemly, and receiving in themselves that recompence of their error which was meet.”
If 7OwO had an incorrect worldview, that would not make him dumb.
If you think that his reasoning behind that position is faulty, then correct it. Don't you want to educate him into being less dumb?
